Scope

This standard is applicable to the rapid detection of the balance coefficient of traction-driven elevators with a rated speed not exceeding 6m/s. This standard provides two rapid detection methods for the balance coefficient of elevators, namely the secondary loading current method and the no-load power method. The secondary loading current method, based on the traditional current-curve method, quickly determines whether the measured elevator's balance coefficient is between 0.4 and 0.5 by only measuring the load current values at 40% and 50% of the rated load. The no-load current method measures the motor running power and car running speed of the elevator in two states: no-load upward and no-load downward, and uses the energy transfer function relationship of the elevator system to establish a mathematical model to solve for the balance coefficient of the measured elevator.
